Relations between the United States and Mexico have been strained since the inauguration of President Trump, who has threatened to dismantle the North American Free Trade Agreement, vowed to make Mexico pay for a border wall and — during his campaign — called Mexican immigrants rapists.

But Mexico has not given up hope that relations can improve, said its foreign secretary, Luis Videgaray.

(CNN)After a period of goodwill during the Obama years, the views of Mexicans toward the United States are souring.

According to a study released Thursday by the nonpartisan Pew Research Center, more Mexicans view the United States unfavorably than at any other time since 2002, when Pew started keeping track. They don’t like President Donald Trump or his border wall proposal, and fewer believe strong economic ties are good for them, compared with two years ago.

Mexico’s Foreign Relations Secretary Luis Videgaray is expected to meet Monday with Gov. Jerry Brown and state legislative leaders in California’s capital. He will later head to Los Angeles to announce support for young immigrants whose protection from deportation is being terminated by Trump and meet with business and community leaders. He also plans a trip to Washington later in the week, officials at the Los Angeles consulate said.

Mexico’s Ministry of Economy and Alibaba will partner to get more Mexican products onto the tech firm’s popular e-commerce platforms. The move aims to help Mexico’s small- and medium-sized enterprises expand internationally and in China — the world’s largest consumer market with a growing middle class. Alibaba, in turn, will provide its technological expertise on logistics and payments, and it will share analytics to help Mexican firms market better to the Chinese.

Energy independence has long been America’s unrequited love. Every president since Richard Nixon has opined on the dangers of the country’s reliance on foreign energy and pledged with equal passion to deliver the U.S. from its evils.
